Solar power generation in aluminum smelters

Solar needs aluminum, but the metal has a carbon

Smelters are designed for constant power, but German firm Trimet has transformed some of its furnaces in an aluminum smelter to adapt to variable power. While smelters need to keep materials in a molten state,

Impacts of aluminum production: A cradle to gate investigation

6 FAQs about [Solar power generation in aluminum smelters]

How much energy does an aluminum smelter use?

The stated aluminum energy intensity of 13.48 kWh/kg Al implies an average power consumption of 4047 MW. For a power plant efficiency of 50%, this translates to a natural gas combustion rate of 27,618 MMBtu/hr. We developed a general model for analyzing smelter cell dynamics with a shell heat exchanger.

Can solar energy be used in aluminum smelters in the Middle East?

While smelters in Australia are considering integrating renewables into their energy supply model as their current energy costs renders them uncompetitive , to date there is no known effort to directly incorporate solar renewables into aluminum smelter operations in the Middle East. Fig. 1.

Where do aluminum smelters get their electricity?

Aluminum smelters in China currently obtain 16% of their electrical power from hydroelectric plants on rivers located primarily in Southwest Yunnan and neighboring Guangxi provinces. Norsk Hydro operates more than 20 hydropower facilities throughout Norway, providing around 10 TWh of clean and renewable energy annually for aluminum production.

Where are aluminum smelters located?

Aluminum smelters are located near low-cost electricity sources, where hydro, coal, and gas are the dominant resources used. The percentage of renewable energy sources used in the primary aluminum smelting power consumption today is a little less than 28% and is almost entirely based on hydro power plants.

What percentage of aluminum smelters use hydro power?

Which power source is used by aluminum smelters in China?

Though thermal power has been the dominant power source for aluminium industry in China, the usage of green power, particularly the hydro power has increased rapidly, Fastmarkets learned. In around 2015, thermal power accounted for around 89% of energy used by aluminum smelters in China, and hydro power about 10%.
